1. Introduction

This Sustainability Management Plan (SMP) has been prepared to assist the design, construction and operation of the proposed mixed-use development at 554-558 High Street Road, Mount Waverley to achieve a range of best-practice sustainable development objectives.

Sustainable Development Consultants has assessed the proposed development and provided input to the design team. This SMP captures initiatives which ensure that the development meets the sustainability objectives of the Monash City Council.

1.1 Site and Development Description

The site is located at 554-558 High Street Road and is currently occupied by different commercial buildings such as a fitness centre, a yoga studio and a used car dealer, which are proposed to be demolished prior to the construction of the development. The site is located within a well-established residential area, approximately 20kms south-east of the Melbourne CBD. A metropolitan train station is located within walking distance of the site which will provide good public transport access for residents to other inner suburbs and the Melbourne CBD.

The proposed development consists of a seven-storey mixed-use building containing 85 apartments above a basement garage with three retail tenancies on ground floor with street frontage on High Street Road.

1.2 City of Monash Requirements

The City of Monash expects the High Street Road development to be designed, built and maintained at a level that provides good practice ESD outcomes as described in the Local Planning Scheme Clause 21.13 “Sustainability and Environment” and the Water Sensitive Urban Design requirements of Local Policy Clause 22.04 Stormwater Management Policy. The development will address the following:

Construction, Building and Waste Management; Indoor Environment Quality; Energy Efficiency; Transport; Water Efficiency & Stormwater Treatment; Building Materials; and Urban Ecology & Innovation.

In order to address these categories, the proposed development will aim for good environmental practice; including compliance with required outcomes using the FirstRate 5 energy assessment tool. This will be in line with requirements of Clause 21.13 of the City of Monash.

Key Council Nominated Objectives from the Clause 21.13 are as follows:

Energy performance: Minimise energy usage; Reduce total operating greenhouse gas emissions; and Reduce energy peak demand through particular design measures (e.g.

appropriate building orientation, shading to glazed surfaces, optimise glazing to exposed surfaces, space allocation for solar panels and external heating and cooling systems).

Water efficiency and stormwater management:

Improve water efficiency; Reduce total operating potable water use; Encourage collection and use of stormwater; Incorporate water sensitive urban design, including stormwater re-use;

Waste Management:

Promote waste avoidance, reuse and recycling during the design, construction and operation stages of development;



Ensure durability and long term reusability of building materials; and To ensure sufficient space is allocated for future change in waste management

needs, including (where possible) composting and green waste facilities.

Transport: Ensure that the built environment is designed to promote the use of walking, cycling and public transport and minimise car dependency.

1.3 ESD Assessment Tools

There are a number of calculators and modelling programs available in Victoria to assess proposed developments against benchmarks set by the Victorian government, local councils and the Building Code of Australia. Different tools are used to assess different aspects of the development including the:

FirstRate5, which covers the thermal efficiency of the building envelope. Model for Urban Stormwater Improvement Conceptualisation (MUSIC), which addresses stormwater

quality considerations.

FirstRate5 assessments tie to requirements that are mandatory for Victoria.

1.3.1 FIRSTRATE 5

The energy efficiency of the apartments’ thermal envelopes has been assessed using FirstRate 5, which is an energy modelling software program to rate dwellings on a 10-Star scale. The tool uses the AccuRate engine (as a nationally recognised energy benchmarking) to rate dwellings based on climate zone, materials used in a structure, positioning, orientation and building sealing. Higher scores are achieved primarily through better material selection, improvements in glazing, and insulation. It is noted that the 2016 BCA (Building Code of Australia) will apply to this development. A representative sample (10 apartments) has been modelled to predict the average heating and cooling energy use of the development. The results of the FirstRate assessments can be found in Appendix 1 of this report.

2. Sustainability Initiatives

The following sections outline the initiatives which will be included in the development and implemented throughout the design and construction process.

These sections, as well as nominating the sustainability initiatives, also identify the party/parties responsible for implementation of the initiative, and the stage at which implementation will be demonstrated. The following are the broad project stages:

1 Design Development Consultants develop conceptual design drawing to a detailed stage suitable as a basis for preparing working drawings - Integration of architectural, services, structure and site attributes

Checking compliance with all statutory requirements, codes and standards

Arranging special surveys or reports as required 2 Construction Documentation Architectural and services drawing sets completed

All specialist reports completed All necessary planning and building consents obtained as required by

authorities 3 Construction All work carried out onsite – site preparation, construction, alteration,

extension, demolition Purchase of all materials / certification Evidence gathering from subcontractors Commissioning

4 Post Occupancy Operation and Maintenance Education – Building Users Guides



2.1 Construction, Building and Waste Management

Initiatives included in construction and waste management promote adoption of environmental initiatives at different stages of the project – not just in the project design stage.

Design Requirements Responsibility &

Implementation

Project Stage

Metering and Monitoring Separate meters (water, hot water and electricity) will be provided for each apartment and tenancy where appropriate.

All common area services (e.g. common lighting, car park ventilation) will be separately sub metered.

Services Consultant

Construction Documentation

Construction Waste Management The builder will develop a waste management plan for the pre-construction, civil works and construction phases. This will include the following:

Waste generation; Any waste systems; Minimisation Strategy; Performance / Reduction targets; Bin quantity and size; Collection frequency; Waste contractors; Signage; and Monitoring and reporting including frequency and method.

The waste management plan will include a requirement for not less than 80% of all demolition, land clearing, civil works and built form construction waste to be recycled or re-used. The waste management plan will require that all hazardous substances, pollutants and contaminants must be managed and disposed of in accordance with all state regulatory requirements. Where these materials are treated or used on site, they must be in accordance with a sanctioned remediation process.

Builder Construction

Documentation

Building User Guide A Building User’s Guide (BUG) will be developed for the staff and residents in apartments. The BUG will be comprehensive and will include training on inspection of the use of systems specific to the development, such as lighting and garbage chute, additional descriptions of systems installed in the building, sustainable transport in the area, and sustainable living suggestions in relation to the development.

Developer Construction

Documentation

Universal Access The development will be designed for universal access in accordance with AS1428.2 to allow patrons with limited mobility to enter and use the premises.

Architects Design

Development

Commissioning of Building Systems Central building services and operational features must be commissioned correctly in order for them to operate as designed and achieve the intended environmental benefits. Attention to commissioning is imperative as this process is commonly performed and/or documented poorly. As a result, a commitment will be made to commission building services to a relevant standard (e.g. AIRAH, ASHRAE, or CIBSE). In addition, simple, low tech controls are included which allow for systems to be managed manually rather than automatically. This will reduce risks and costs associated with the commissioning and maintenance of complex control systems, and ensure that systems have a longer operational life.

Implementation

Project Stage

Operational Waste The development will be provided with a conveniently accessible dedicated central storage room at the basement level which will be sufficiently sized for both waste and recycling.

Provisions will also be made for the inclusion of both waste and recycling receptacles within apartments to help encourage occupants to separate their waste at the point of disposal.

2.2 Indoor Environment Quality

Indoor Environment Quality (IEQ) addresses initiatives which help to create a healthy indoor environment free from toxins with ample supply of daylight and outside air.


Implementation

Project Stage

Volatile Organic Compounds (VOCs) All paints, adhesives and sealants and flooring will not exceed limits outlined in Appendix 3. Alternatively, products will be selected with no VOCs. Paints such as eColour, or equivalent, should be considered.

Architect Construction

Documentation

Formaldehyde Minimisation All engineered wood products will have ‘low’ formaldehyde emissions, certified as E0 or better. Alternatively, products will be specified with no Formaldehyde. Emissions limits are listed in Appendix 3. Products such as Ecological Panel – 100% post-consumer recycled wood (or similar) will be considered for use within the development.


Documentation

Acoustic Comfort Acoustic comfort will be achieved in the dwellings by limiting the internal ambient noise levels. Apartments and commercial tenancies will be constructed to ensure good acoustic separation between spaces.

Air-conditioning units will be placed away from windows were possible.

Services Consultant

Architect Design

Development




Implementation

Project Stage

Daylight Access & Improvement All living areas, bedrooms and commercial tenancies will have access to an external window. The depth of living areas from a window has been limited to 8m for most apartments, allowing daylight to spread evenly within the space. All glazing to the living areas will have a minimum 60% Visible Light Transmittance (VLT). Daylight penetration through windows/openings will be enhanced with the use of light internal colours, allowing for a better internal reflection of daylight.


Documentation

Artificial Lighting Level A higher illuminance level will be provided for task areas such as the kitchen sink/benches and over bathroom/ensuite basins to ensure that there is adequate light to carry out tasks in these areas.

Services Consultant


Mechanical Exhaust - Kitchens All kitchens will have a separate dedicated exhaust fan (range hood) which will not be recycled to any enclosed space within the building.

Services Consultant


Glazing The apartments will be fitted with double glazed windows. The double glazing brings multiple benefits to the apartments such as a better thermal performance and the reduction of the amount of condensation that forms on the inside of the glass which will help prevent the formation of mould in the units.


Documentation

Effective Natural Ventilation Apartments, commercial tenancies and common areas will be fitted with operable windows to promote natural air movement through the spaces. This will provide opportunity for passive air changes within each different area which helps reduce the potential build-up of mould and other airborne toxins. Natural ventilation can also, when weather conditions are suitable, reduce the need for mechanical cooling. Fly screens, window locks and door catches will be included to encourage and aid natural ventilation in the apartments.

2.4 Transport

The High Street Road site has been assessed using the “Walk Score” locational performance tool. The tool was developed in 2007 by Front Seat using the Google Maps tools. This tool takes into account the number of facilities within close proximity and provides a numerical score of between 1 and 100, with 1 being heavily car dependant with access to community facilities that are located some distance away, and 100 reflecting a location that is easily accessible to abundant facilities by foot. The High Street Road development achieves a score of 77 out of 100, which is classified as “Very Walkable.” High Walk Scores above 70+ indicate that the building occupants can complete most daily errands without requiring a car.

3. Implementation of Initiatives

The proposed High Street Road development will meet the good practice ESD requirements set by the City of Monash through a number of initiatives such as the efficient thermal performance of the buildings’ envelope and the reduction in greenhouse gas emissions through the use of efficient air conditioning, the installation of 10kW (min.) of solar PV panels; as well as reduced environmental impact during the construction stage through the specification of sustainable materials and a mindful construction team.

The initiatives that have been included within this SMP have a proven track record to serve their individual purpose and can be easily maintained with any failures generally being obvious to the occupants of the development. This helps to ensure the ongoing sustainability of the development as the systems installed in the beginning are maintained for purpose throughout the life of the development.

With appropriate implementation, management, monitoring and maintenance the initiatives outlined within this report will serve to provide the occupants with lower running costs, as well as benefit the surrounding environment of the 554-558 High Street Road, Mount Waverley development with an environmentally and economically sustainable development.



Appendix 1 FirstRate5 Sample Energy Rating Results

The FirstRate energy rating program is the primary modelling method used in Victoria to indicate the required energy for heating and cooling based on the building’s thermal envelope. It does not take into account any heating or cooling systems installed; it only assesses walls, roof and floor materials; levels of insulation, building orientation, glazing and the area layout. The 554-558 High Street Road development is located in Climate Zone 62 (Moorabbin) and is required to achieve an average of 6.0 Star (125MJ/m2) with no dwelling lower than 5.0 Star as per the Building Code of Australia (BCA) requirement. Developments should aim for a 10% improvement (average ratings of 6.4 stars – 112.5MJ/m2) for energy rating performance to align with ESD Best Practise principles.

Building Fabric Element Description

External Walls

All external walls will require an additional R2.5 insulation to be added.

Some options include:

CSR Bradford Gold Wall Batts (R2.5) Knauf Earthwool External Wall Batts (R2.5)

Insulation material with minimum 20% recycled material content will be selected. The options recommended above go beyond this requirement.

Party Walls Party walls will require acoustic insulation.

Internal Walls Internal walls do not require additional insulation.

Floor Floors are assumed as suspended concrete slab. Additional R2.0 insulation is to be added when the floor is located above the car park or an open space.

Floor Coverings Floor coverings are assumed as carpet for bedrooms, tiles for bathrooms / ensuite and floating timber for the living room and

Roof Insulation Roofs between levels have been modelled as suspended slabs and will need an additional R2.0 added insulation where located under a balcony/terrace.


CSR Bradford Gold Ceiling Batts (R2.0) Knauff Earthwool Ceiling Batts (R2.0)

Top roofs have been modelled as metal deck roofs and will require R5.0 insulation to be added.


CSR Bradford Gold Ceiling Batts (R5.0) Knauff Earthwool Ceiling Batts (R5.0)

Windows and Glazing Awning / Casement windows are required to have window system thermal performance values of:

Glazing Properties - U value = 4.5, SHGC =0.50

Fixed and sliding windows are required to have window system thermal performance values of:

Glazing Properties - U value = 4.5, SHGC =0.61

These values are commonly found in clear double glazed argon filled windows with aluminium frames.

Building Sealing All doors, windows, exhaust fans and openings will be sealed so as to not allow for air infiltration into the apartments.

Downlights All recessed down light fittings that have openings allowing air to pass through to a ceiling cavity (e.g. Adjustable down lights) shall be fitted with a cover that allows for ceiling insulation to closely enclose the sides and top of the down light.

Note: The above building elements may vary as the plans are refined for building approval, however the average building energy rating performance of 6.4 Stars (112.5MJ/m2) will be maintained as a minimum.

** Please note that at the time of the assessment most window sizes and location were not specified thus assumption have been made. This will be refined once more information is available.



Appendix 2 Stormwater Management

Objectives

The quality and quantity of stormwater leaving a site can have a significant impact on the surrounding infrastructure and waterways. Impervious surfaces move water quickly and efficiently out of built up areas straight into stormwater infrastructure, which in turn quickly moves the untreated water into natural watercourses. This process does not treat the stormwater and as the water flows into natural water courses, it causes erosion and pollution of those waterways with the rubbish, sediments, pathogens, and other pollutants off the impervious surfaces into the stormwater drains.

The City of Monash has recognised the importance of managing stormwater flow and water quality. As a result, a local planning policy, Clause 22.04 “Stormwater Management Policy”, has been introduced into the City of Monash Planning Scheme.

The relevant objectives that form part of the Stormwater Management Policy include:

To minimise the introduction of polluted stormwater to the drainage and waterway system. To promote and enhance the contribution the drainage system can make to environmental, social and

economic benefits to the region. To encourage the provision of on-site retention systems so that stormwater discharge is maintained at

pre-development levels.

New developments must also encourage the use of measures to prevent litter being carried off-site in stormwater flows. The proposed development has addressed these requirements by identifying the impervious surfaces within the site and implementing treatments to mitigate the impacts and amount of stormwater leaving the site. To assess these initiatives, the MUSIC tool – which is an industry accepted tool – was used to determine the impact of these initiatives between the pre-development conditions and the post-development conditions.

Site Characteristics

For the purposes of the stormwater assessment, the development has been assessed under pre-development conditions and post development conditions to determine the impact of the proposed initiatives. The pre and post development site have been delineated into basic surface types listed below:

Pre-Development

Site area of 2,619m2 with 95% considered as impervious areas and 5% as pervious (landscaping, bare ground).

Post-Development

Site area of 2,619m2 considered as 100% impervious. Roof catchment area of 1,023m2 connected to a rainwater tank on site; and Remainder of site of 1,596m2 comprised of balconies, terraces, unconnected roof.

Stormwater Management Initiatives

Stormwater treatment initiatives will need to be implemented. The following section presents the different surfaces that have been identified for treatment, and the required treatment. The initiatives to manage stormwater flows for the building area will underpin the overall performance of the building and its ability to meet stormwater management objectives.

will also be connected to the tank.

Remainder of site 1,596m2 Runoff from the remainder of site and any overflow from the above mentioned treatment measures will be directly released at the legal point of discharge.

Stormwater quality modelling results

The results from the MUSIC assessment between pre and post-development are as follows:

The results above show that the implementation of a retention system on-site will result in a reduction of stormwater discharge (14.9% flow reduction) as compare to the pre-development levels. With the implementation of this retention system, less polluted stormwater will be introduced to the drainage and waterway system in line with policy objectives.

The retention system will reduce the current environmental impact of the stormwater runoff of the site on its surrounding environment. It will allow occupants to use rainwater within their apartment reducing directly their mains water consumption and water bills providing local environmental, economic and social benefits in line with policy objectives.

MUSIC Input

Listed in the tables below are the basic inputs used for the MUSIC model (Figure below). All low and high-flow bypass volumes were left at default (0m3/s and 100m3/s respectively). The following guideline was used in the creation of the model:

Daily Demand

The daily rainwater use for the toilets has been estimated to be equivalent to 0.492 kL/day. This estimation is based on 40 occupants (15 occupants for retail areas and 25 for ground and first floor apartments) using two and a half flushes per day. 4 WELS Star rated toilets consume 4.5L per full flush and 3L per half flushes thus each occupants will use 12L/day for toilet flushing.

Stormwater Runoff Treatment during the Construction Stage

Treatment – Various

Stormwater management in the construction stage will include measures which will be put in place to minimise the likelihood of contaminating stormwater discharge from the site as well as reduce the velocity of the flows generated from the building as it is being constructed. This will mean ensuring buffer strips are in place, and the site will be kept clean from any loose rubbish. More information is available from “Keeping Our Stormwater Clean – A Builder’s Guide” by Melbourne Water3. The diagram below is an illustration of the various objectives which assist in minimising the impacts of stormwater runoff typical during the construction phase. Typical pollutants that are generated from a construction site during a rainfall event include:

Dust Silt Mud Gravel Stockpiled materials Spills/oils Debris/litter

Figure 11: Stormwater will be effectively managed during construction phase according to the requirements listed in “Keeping

Our Stormwater Clean – A Builder’s Guide”.

To reduce the impacts and minimise the generation of these pollutants the following measures are proposed. The symbols embedded within each image are typically used for Construction Environmental Management Plans.

Gravel Sausage filters – to be placed at the entrance of pits/side stormwater inlets. These permeable sacks will filter the suspended soils and sediments and any other litter carried by the stormwater to prevent the pollutants entering the system

Silt Fences Under Grates - Silt fence material may be placed under the grate of surface-entry inlets to prevent sediment from entering the stormwater system.

Temporary Rumble Grids – these are designed to open the tread on tires and vibrate mud and dirt off the vehicle (in particular the chassis). This will heavily minimise the amount of soil/dirt deposited on local streets where it can be washed (by rainfall or other means) into the stormwater drains.

Conclusions and Recommendations

With the implementation of rainwater tank storage system for the roof runoff, the overall flow from the site during rainfall events have been significantly reduced. Overall the development has reduced the outflows and improved quality of stormwater runoff from the site significantly compared to the pre-development conditions

The builder will also be required to adhere to Melbourne Water’s stormwater management guidelines during the construction stage.
